This is the theme of the article, Top 5 Engineering Destinations to See Before You Die, on the website Interesting Engineering:
As the introduction to the article states, "Whether they're world wonders or feats of modern engineering, all of these places possess certain awe-inspiring qualities sure to make your trip worth it."
These are the five destinations chosen in the article (all images are from the Interesting Engineering article):
The description of each destination is rather short, but focuses on the reason it is on the list. Students could write short descriptions in similar style for other destinations they might have chosen. Special focus could be put on the top engineering destinations in students' own countries. And, of course, if students (or teachers) have visited any of these destinations, their further impressions could be added to the discussion.
